Description Enhance Your Property with a Chartwell Green uPVC Casement Window Introduce a sophisticated country-home aesthetic to your living space with our custom-engineered Chartwell Green uPVC window. This distinctive configuration features a side-hung opening sash divided by a central transom bar, paired with a full-height fixed pane. It is an ideal structural layout for adding architectural detail to narrow openings, stairs, or utility spaces while offering controlled ventilation. The traditional pastel green tone injects instant kerb appeal into both classic renovations and modern builds alike. Every single one of our uPVC casement windows is built to order, ensuring precision engineering, effortless operational movement, and long-term durability. Exceptional Insulation & High-Performance Weatherproofing Keep your home comfortable through every season while reducing high energy costs. Our high-specification double glazed uPVC windows utilize a 70mm thermally optimized multi-chambered frame layout combined with 28mm argon-filled glass units and a warm-edge spacer bar system. This combination yields a superb A-rated 1.3 W/m²K U-value, blocking cold drafts out during winter storms and reflecting excessive summer heat. To protect your interior from dampness and leaks, the frame relies on patented double-action bubble gaskets that compress evenly for an airtight barrier that satisfies all current UK Part L Building Regulations. Comprehensive Security Built for Total Peace of Mind Securing your household is at the center of our manufacturing process. Each Chartwell Green uPVC window is built with a heavy-duty multi-point locking system and a lockable, push-button handle designed to stop forced intrusion attempts. Additionally, the double-glazed panels are internally beaded, meaning the glass units cannot be extracted or tampered with from the exterior side of your house.
